SMOKE-PIPE REGISTER.

SPECIFICATION forming part of Letters Patent N 0. 689,697, dated December 24, 1901- Application filed November 13, 1900. Serial No'. 36,367. (No model.)

To @Z whom it may concern:

Be it known that I, WILLARD S. TUTTLE, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Smoke- Pipe Register, of which the following is a full, clear, andeXact description.

The invention relates to heating-drums or smoke-pipes usually extending from a room through the ceiling and the ioor above into van upper room and connecting with the chimney to carry off the smoke and gases and radiate heat into the room above to heat the same.

The object of the invention is to provide a new and improved smoke-pipe register forV holding a smoke-pipe in position in the fioor and arranged for obtaining desired control of the heated air passing from a room below to the room containing the register.

The invention consists of novel lfeatures and parts and combinations of the sam e, as will be fully described hereinafter and then pointed out in the claim.

A lpractical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure lis a plan view of therim provement with the smoke-pipe shown in position and in section. Fig. 2 is a sectional side elevation of the same on the line 2 2 in Fig. l. Fig. 3 is a plan view of the improvement with the smoke-pipe removed and the center piece in position, and Fig. 4 is a sectional side elevation of the same on the line 4 4 in Fig. 3.

The improved smoke-pipe register consists, essentially, of a register-body A, having an annular ange A', resting on the floor B, and an annular iiange A2, extending downwardly and fitting against the wall or opening B' in the oor B. (See Figs. 2 and 4.) From At-he flanges A' A2 extends inwardly an annular perforated portion A3, over which operates a ring-shaped perforated regulator C, adapted to be turned by the operator engaging a knob or handle D, integral With the regulator O. By turning the regulator C its perforated portions can be moved to coincide with the perforations in the portion As of the register-bod y A, so that communication can be established 'through the body when the'perforations coinF eide, or the communication be cut olf when the perforations are moved out of coincidence by the operator turning the regulator C accordingly.

The inner portion of the regulator-body is ring-shaped, as shownl at A4, and from this ring extend inwardly-spaced lugs or projections A, forming abutments for' a smoke-pipe E to hold the same in position and to leave sufficient space between the ring and the smoke-pipe for the circulation of heat from the lower room up to the upper room along the outside of the smoke-pipe, as will be readily understood by reference to Figs. l and 2.

When the smoke-pipe E is not in positionsay during the summer-then the central opening in the register is closed by a center piece F, having perforations and resting on the lugs or projections A5, thus forming a seat for the center piece. The outer edge of the center piece fits close to the ring-shaped inner end A4 of the register-body, thus enabling the register to be closed perfectly.

In the center of the center piece F is arranged a pivot G, on which is mounted a perforated'regulator H, extending, preferably,on the under side of the center piece and having a handle I, reaching through one of the perforations in said center piece, to permit the Voperator to turn the regulatorH and bring its perforations in or out of coincidence with the perforations in the centerpiece. On the under side of the center piece F are arranged a pair of dependinglugs F', spanning one of the projections or lugs A5, so that the center piece is held against movementwhen the operator manipulates the handle I for turning the regulator H. When the center piece is in position, communication between the lower and upper room by way of the register can be entirely shut off by turning the regulators C and H into such positions that their perforations do not coincide with the perforations in the body portion A3 and the center piece F, and when lit is desired to establish communication between the two rooms then such communication can be had either' at the body p0r tion by turning the regulator C or at the center piece by turning the regulator H or by turning both regulators, if desired. Thus IOC the register can be entirely closed to cut OE communication between the two rooms, or it can be partly or fully Opened, as desired, to establish more or less circulation of air between the two rooms by way Of the register. Hitherto this has been accomplished by having two center pieces, one solid and one open. TO Open or close the center, it was necessary to substitute the one for the other. Itis understood that when the smoke-pipe is taken Out the center piece can be readily placed in position, and when it is again desired to use the smoke-pipe the center piece can be taken out and stored away until it is required.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- A smoke-pipe register, comprising an an- WILLARD S. TUTTLE.
